OIL BURNER.

Application filed. March 22, 1923.

My invention relates to improvements in oil burners, the object being to produce an efficient, rugged, silent non-flooding and cheap burner.

I obtain these objects by the mechanism shown in the accompanying drawing in which Figure 1 is a side view of the burner assembled in an upright position. Figure 2 is a vertical section through the center of the burner. Figure 3 is a cross section of the burner taken on the line 3-3 of Figure 2. Similar letters refer to similar parts throughout the several views.

Referring now more particularly to the characters of reference as illustrated. in Figure 1 the letter 0 indi ates a fuel supply pipe attached to the fuel inlet at A, preferably a check valve of the ball type, wherein there is a slight annular space around the ball K enough to permit the proper amount of oil to pass for starting purposes. The aperture G in the diaphragm M connects the primary vaporizing chamber B with the secondary var porizing chamber D which is connected thru the openings E to the vapor manifold F which in turn opens to the atmosphere thru the pinhole G.

To the generating pan J are attached the legs I that act as supports for the rest of the burner which sets loosely thereon. The pipe L is a drain and may be used to remove carbon also. A petticoat H acts as a muffler and also concentrates the heat. In principle this device operates as follows; the ball K is pressed downward upon its seat by static pressure from oil in the supply pipe O which extends up ward high enough to produce the proper pressure. The vaporizing chambers B and D and the vapor manifold F are first heated to the proper temperature by burning an inflammable liquid, preferably alcohol, in the generator pan Jt Then assuming the supply pipe 0 to be full of oil, the leakage passing the ball K? (as before mentioned) will drip in chamber B which is new hot, where expanding and vaporizing it will exert suficient pressure Serial No. 62652595 upon the ball K to lift it upward and open until forced downward and shut by pressure of the oil in the supply pipe 0 thus producing anautomatic feed that will prevent flooding. The ball K being solidmoves open under the pressure of the gas. The movement of the fluid gas in the chamber B then gathers and mixes with just enough of the fluid oil from the pipe 0 to keep a sufficient supply in the said cha1nber B to keep the burner functioning. The oil is only partially vaporized in chamber B but passed thence through the hole (1 into chamber D where complete vaporization takes place. The vapor then passes through the holes E through manifold F and out through pinhole G impinging upon the bottom of chamber D which being hot, ignites the vapor. Thepetth coat H concentrates .the flame and heat around chamber B and D thus promoting complete vaporization. In fact the entire apparatus becomes red hot and therefore it is preferable to use metal with a "high melting temperature in these burners.

I am aware that prior to my invention, oil burners of various kinds have been made and patented, therefore I do not claim such a combination broadly but that which I do consider as new and useful and for which I claim Letters Patent is as follows A hydrocarbon burner comprising a primary and a secondary vaporizing chamber lying immediately adjacent one another and separated by a diaphragm having a center orifice communicating from one chamber to the other, the walls of the secondary chamber having opposed outlets closely adjacent the diaphragm whereby generated in the first chamber will discharge through the diaphragm orifice and strike the opposite end of the seconday chamber and be expanded and flow evenly out of the opposed outlets, and a manifold con'imunicating with the opposed outlets and having a common discharge outlet at a spaced distance from the secondary chamber and discharging thereagainst.
